Database migration · Coimbatore
Azure database migration services in Coimbatore.
Plan the move before the switch.
Bring your databases, applications and operating requirements into one migration plan. Akkenna helps scope the assessment, preparation, rehearsal and validation needed for a move to Azure.
Illustrative migration path
Clear decision points.Planned around the source and target
- 01
Understand the source
Inventory, dependencies and operating constraints.
- 02
Prepare and rehearse
Check target readiness and test the agreed method.
- 03
Approve the cutover
Confirm the window, responsibilities and acceptance checks.
- 04
Validate the Azure target
Review data, application behaviour and handover.
01 / Start with the current system
Know what is moving.
Know what depends on it.
A database rarely operates alone. The assessment brings technical dependencies and business constraints together before a target or migration date is agreed.
Inventory the source
Record the database engine and version, size, growth, important objects and existing backup arrangements. Identify the information needed to assess compatibility.
Map the connections
Identify applications, reports, scheduled jobs, integrations and users that read or write data. Name the owners who can review and test each dependency.
Set the constraints
Discuss service hours, critical business periods, acceptable interruption, recovery priorities and decision makers. These requirements shape the migration approach.
Assessment output: an agreed inventory, open questions, compatibility findings and a proposed sequence. Unresolved dependencies remain visible in the plan.
02 / Define the engagement
A clear scope for each stage.
Agree the work, deliverables and review points before implementation. Application changes and work on systems outside the database are identified separately.
- 01
Assessment and migration plan
Review source information, dependencies and constraints. Document the proposed approach, assumptions and acceptance criteria.
- 02
Target preparation
Scope the Azure environment, connectivity, access and configuration tasks required before data movement begins.
- 03
Schema and application readiness
Identify objects, queries, jobs and connection settings that may need changes. Agree who implements and tests those changes.
- 04
Migration rehearsal
Exercise the agreed migration method in a suitable test environment. Record timings, failures and corrective actions.
- 05
Cutover and validation
Follow the approved change plan, coordinate application checks and compare the results with the agreed acceptance criteria.
- 06
Documentation and handover
Record the final configuration, access responsibilities, outstanding issues and the agreed arrangements for ongoing operations.
03 / Source and target readiness
Choose the destination around the workload.
The right target and migration tooling depend on the source database and application requirements. Compatibility is checked for the specific combination before it is included in the plan.
| Decision area | What we review | What the plan records |
|---|---|---|
| Compatibility | Source version, database objects, application behaviour and target requirements. | Supported approach, required changes, limitations and unresolved questions. |
| Capacity | Data size, growth, workload patterns and expected operating needs. | Initial sizing assumptions and the checks used to review them. |
| Connectivity | How applications and migration tools will reach each environment. | Network prerequisites, responsible teams and connection tests. |
| Permissions | Access needed for assessment, migration and ongoing application use. | Named owners, agreed permissions and when temporary access is removed. |
| Recovery | Existing backups, restoration requirements and the handling of new writes. | Recovery procedure, validation tasks and cutover decision authority. |
The proposal identifies the selected Azure service and migration method after assessment. Moving to Azure alone does not establish performance, cost savings or compliance.
04 / Prepare, then practise
Use the rehearsal to improve the plan.
A reviewable test run gives the team evidence about the sequence, timings and checks. Findings become changes to the plan before a production move is approved.
Prepare the test
Agree a suitable environment and representative data. Define the access, backups and application checks needed for the rehearsal.
Output: rehearsal checklist
Run the sequence
Follow the proposed steps, record timings and capture issues. Include the people responsible for dependent application changes.
Output: execution record
Review the results
Compare data and application behaviour with the acceptance criteria. Review recovery steps and any gaps the test has revealed.
Output: findings and actions
Agree readiness
Resolve blocking issues or revise the approach. Confirm who approves the change window and communicates the production decision.
Output: reviewed cutover plan
05 / Cutover and recovery
Make the switch a decision.
Not an assumption.
The cutover plan names the change owner, sequence, communication points and checks. It also explains what the team does if the move cannot be accepted.
Expected interruption is assessed from the source, target, workload and chosen method. The rehearsal informs the agreed window; it does not create a zero-downtime guarantee.
Confirm the entry conditions
Check access, backup readiness, application owners and the handling of writes during the move. Confirm that required checks can be completed within the window.
Accept, pause or recover
Use agreed criteria and a named decision maker. Record issues and communicate whether to proceed, extend the review within agreed limits or invoke recovery.
Account for changed data
Define how data written during or after cutover will be handled. Returning to the source may require reconciliation; recovery is more than changing a connection setting.
06 / Validate the result
Check the data.
Check the business workflow.
Completion is measured against agreed acceptance checks. A transferred database still needs to be reviewed in the context of the applications and people using it.
Data checks
Compare agreed record counts, selected totals and representative records. Investigate discrepancies and document the checks completed.
Application journeys
Test representative reads, writes and business actions with application owners, including relevant reports and integrations.
Jobs and connections
Review scheduled tasks, connection settings and external dependencies. Record anything deferred or outside the migration scope.
Access and permissions
Check required application and user access, and review temporary migration accounts against the agreed removal plan.
Workload behaviour
Review selected query and application timings against the agreed baseline. Separate migration defects from later optimisation work.
Operational readiness
Review backup arrangements, monitoring ownership and incident contacts. Confirm the acceptance decision and outstanding actions.
07 / Ownership and costs
A clear handover.
A realistic operating plan.
The migration engagement and the ongoing cloud environment have different responsibilities. Make both visible in the proposal before the work starts.
Agree who owns what
Name the people responsible for business approval, database access, application changes and day-to-day operations.
- Cloud subscription, billing and administrative access
- Application releases and business acceptance
- Backups, monitoring and ongoing maintenance
- Temporary access removal and documentation
- Support scope, contacts and escalation arrangements
Make the cost assumptions clear
The estimate should separate migration work from infrastructure and third-party costs. Review changes to scope as assessment findings emerge.
- Assessment, implementation and agreed review rounds
- Azure resources used during rehearsal and production
- Any parallel environments retained during transition
- Licensing, tooling and applicable data-transfer costs
- Optional application changes or ongoing support
08 / Before we begin
Azure migration questions, answered.
Share the current environment and what you need to change. The first discussion helps identify the assessment and decisions required.
Can you migrate our current database to Azure?
We start by reviewing the database engine and version, dependencies and proposed Azure target. The supported migration approach and any required changes need to be confirmed for that combination before the implementation scope is agreed.
Will the migration require downtime?
That depends on the source, target, workload and migration method. We agree the interruption constraints, test the proposed sequence and plan the change window from those findings. We do not promise zero downtime.
How do you check that the data has moved correctly?
The plan defines validation checks such as agreed record counts, selected totals, representative records and application journeys. Findings are documented and reviewed against acceptance criteria with the responsible owners.
Are application changes included?
They are included only when specified in the scope. Connection settings, queries, jobs or integrations may need changes. We identify the owners and testing responsibilities so those dependencies are accounted for before cutover.
How are migration costs and ongoing support handled?
The proposal separates the migration tasks from cloud consumption, licensing and any ongoing support. Support coverage, responsibilities and fees are agreed explicitly; they are not assumed to be included indefinitely.
What do you need for an initial discussion?
Share the database engine and version, approximate size, connected applications, current hosting, migration goal and timing constraints. An overview is enough to start; do not send passwords, access keys or a production database through an enquiry form or WhatsApp.
09 / Plan your migration
Start with the system you have.
Define the move you need.
Tell us what runs on the database, why you want to move and the constraints that matter. We will help shape the next assessment and a reviewable migration scope.
